Abstract

This device provides an audio output device that allows simultaneous use of speakers and earphones. [Solution] This audio output device comprises an audio input unit 6, a speaker 2, and an earphone connection terminal 4. It has an audio branching unit 8 that branches the audio signal input from the audio input unit into an audio output system 9 for the speaker and an audio output system 10 for the earphones. The audio output system for the speaker is provided with a speaker volume control unit 3, and the audio output system for the earphones is provided with an earphone volume control unit 5. This allows for simultaneous output of sound from both the speaker and earphones even when earphones are connected. The structure branches the audio signal for the speaker and earphones, and provides independent volume control units for each, thus eliminating the inconvenience of conventional home audio devices where the audio output from the speaker stops when earphones are connected.
